“…As the pressure is boosted, the difficulty of compression for CO 2 also increases. These correspond with the gas characteristics under high pressure. , Besides, the density of acetic acid is found to have a positive linear relationship with pressure, which is similar with the characteristic of liquids, such as water and ethanol. − …”

Using a high-pressure phase equilibrium apparatus and vibrating-tube densimeter, phase transition pressures of CO 2 (1) + acetic acid (2) binary systems with x 2 = 0.000, 0.107, 0.163, 0.222, and 1.000 were measured under temperatures from 308.15 to 338.15 K. Besides, the densities at the same composition and temperature under pressure from 15 to 45 MPa were also detected, and the volumes of mixing (Δ V m ) were calculated. Three prediction models (SRK EOS, PC-SAFT EOS, and TS model) were introduced to predict and correlate the density of binary systems, which was found to have positive relationships with temperature and acetic acid concentration and a negative relationship with pressure. Thereinto, the variation trend of CO 2 density with pressure tends to be flat under high pressure, and which of acetic acid density increased linearly with pressure. Δ V m are negative, and their absolute value increases with the increase of temperature and the decrease of pressure. The work herein could provide a theoretical guide and basic data for supercritical CO 2 extraction technology and CO 2 application in oil field development.

We present a wide-ranging correlation expressed in terms of temperature and density for the viscosity of ethanol based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state from the triple point (159 K) to 620 K and at pressures up to 102 MPa. Comparisons with experimental data indicate the estimated uncertainty of the correlation is 4.2 % (at the 95 % confidence level) for the liquid and supercritical phase at pressures up to 102 MPa, and 2 % in the gas phase. Furthermore, for calculating viscosity values at 0.1 MPa, an additional correlation is proposed, valid from the triple point to the boiling point with an estimated uncertainty of 2.3 % (at the 95 % confidence level).
